Hello all.
I’ve just finished creating the url shortener web application for the back end certification. However, before I can mark the challenge, I need to deploy it to heroku. Upon deployment, the Heroku app fails to load (even my views page for instructions), even though it worked for me locally. I suspect this is an issue with my setup of MongoDB but I’m entirely lost. Below I have pasted my github link and my Heroku logs upon deployment. Any help is appreciated.

I think this is the problem.
You had the db local during development (127.0.0.1 - localhost ip address), so now you need to setup a db for production.
mLab provides a free mongodb https://mlab.com/
Get an account and change the connection string to the db you create on mLab. When you make the db, you will also have to create a user account for the db to be able to access it (seperate from the mLab account).
@sfallmann
Ok so I understand what you’re saying, but I don’t understand how to do what you’re saying. I went to the mlab website and created a new database but when I looked up how to connect a database with mLab, the instructions are not applicable to me because what the instructions say are not what appear on my screen. What do you recommend I do?
I’m not sure where you are running afoul in the instructions.
When you create the db, you should be able to click on it and above it should be the connection string info. You also have to make a db user to connect to the db and substitute the username and password in the appropriate spot within the provided connection string.
I looked at your repo for this project and found this in routes/index.js:
mongoose.connect(process.env.MONGODB_URI || process.env.MONGOHQ_URL || process.env.MONGOLAB_URI || 'mongodb://localhost/short_urls');
According to your code, you need to set the Heroku environment variable MONGOLAB_URI to the string
Right now, since all of the environment variables are empty, the last value for the localhost connection string is used.
Heroku - Configuration and Config Vars
@sfallmann
What I mean to say I understand the instructions, but the instructions don’t match up with what’s on my screen. I do not have the connection string info when I log into the site, so I’m not entirely sure what to do. Additionally, how would I go about setting the Heroku environment variable MONGOLAB_URI
Here’s a screenshot of my page:
See here to set up heroku env variables . https://devcenter.heroku.com/articles/heroku-local#set-up-your-local-environment-variables
You can also do it like so -
Create MongoDB Deployments like so
@yasserhussain1110
The Heroku variables make sense, however I still don’t understand how to connect to the database. I have a similar screen to the one you have, however I do not know how to connect to the database or get the url to the database for my app.
EDIT: I just figured out that I was creating the wrong kind of database I was creating a private environment instead. I’ll stay updated on the progress.
@yasserhussain1110 @sfallmann
So I applied the changes both of you provided me and it worked, well for a little bit. I was able to reach the homepage, and I was able to generate one short URL, however when I tried to go to that short URL something failed and the project broke again. I’ve pasted my console dump below but I think it has to do with an error it has reading the database.

You’ll need to debug this. Its hard to say what went wrong just by looking at this log.
TypeError: Cannot read property ‘original_url’ of null
This error line is of interest.
Use console.log to check why the value is null.
I just looked at your github.
Use .gitignore to ignore -
node_modules & npm-debug.log
You have added .gitignore. But the point of .gitignore is that we don’t want to track node_modules and debug log with git.
We only track the primary source code via git. Anything which can be generated is not tracked.
All the libs within node_modules are sort of “generated” because they are already specified by your package.json file.
So now run these commands -
git rm node_modules/ -r
git rm npm-debug.log
git commit -am "Removed dependencies"
git push -u origin master
This will remove those from git.

@yasserhussain1110 I did what you said. I tried running it locally again to log out any problems and the weird this is that it works locally with 0 changes but it does not work when I try it on heroku. Does this narrow down my options of problems?
Checking local logs won’t help. Run it in production and check the production logs. Clearly this issue is related with your app setup and not your code logic, because it works locally.
